How do i group dates automatically

[Ashish Balki]

I have to cluster 5 dates into one group. I have year-long dates which mean I should have (365/5=)73 groups starting from 1st March. How do I do it in excel? Attached is the excel file for 1 quarter.

Assuming each group is 5 days long starting on 1 April 2018
In cell B2: =INT((A2-DATE(2018,4,1))/5)
copy down
